Abstract
864,683. Acoustic reflectors and resonators. DECCA RECORD CO. Ltd. July 6, 1959 [April 8, 1958], No. 11079/58. Class 13. [Also in Group XXXIX] A loud-speaker is mounted at or near the top of an upright tube which is internally divided to form a folded resonant pipe by means of a substantially vertical partition, such as a second tube which may be either concentric (Fig. 1) or eccentric (Fig. 7) with the first, either the inner tube (Fig. 1) or the space between the tubes (Fig. 7) being closed at the bottom. The open lower end of the outer tube has an external flange 95 and is supported clear of the floor by three or more feet 96; it may contain an amplifier and/or an acoustic filter, e.g. a roll of corrugated board. The top of the outer tube may support a soundreflector 23 and a lamp 12, Fig. 1.
